Abstract

La presente invenzione riguarda un film biodegradabile preparato mediante legame dell'amido e delle catene di polietilene impiegando polietilene, che è una poliolefina avente una applicazione generale la più ampia, un agente di accoppiamento come anidride maleica, anidride metacrilica o maleimmide, che si legano con l'amido ed il polietilene, ed un comanomero catalitico acido come acido acrilico e/o acido metacrilico, ed un procedimento per la loro preparazione.La presente invenzione è stata realizzata variando l'agente di accoppiamento come anidride maleica, anidride metacrilica o maleimmide in una quantità di 0,01-10% in peso, il comanomero catalitico acido come acido acrilico e/o acido metacrilico in una quantità di 0,01-10% in peso, e l'iniziatore radicalico in una quantità di 0,01-1,0% in peso, sulla base della quantità di polietilene, e fu applicata l'estrusione reattiva per abbassare il costo di produzione tramite semplificazione del procedimento.
